MACHINE FOR BARBING FENCE-WIRES.

SPECIFICATION forming part of Letters Patent No. 243,683, dated July 5, 1881. Application tiled May 3, 1881. (No model.)

To all whom @t may concern:

Be it known that I, FRA-NCIS L. BESTOR, of Sigourney, in the county of Keokuk and State of Iowa, have invented a certain new and useful Improvement in Machines for Barbing- Fence-Wires, of which the following is a specitication.

The object I have in view is to produce a simple and efficient machine for forming and securing upon fence-wires the barb for which Letters Patent were granted September 17, 1878, to Charles H. Baker and myself; and my invention consists in the peculiar devices employed by me for this purpose, as fully hereinafter explained, and pointed ont by the claims.

In the accompanying drawings, forming a part hereof, Figure l is a top view of the principal parts of my machine; Fig. 2, a section through one of the hollow shafts and tubes; and Figs. 3, 4, 5, and 6, views of the tubes in the different positions they assume when forming and securing a barb.

Like letters denote corresponding parts in all the figures.

A and B represent two hollow shafts, which are mounted respectively in journals a a and b b in the same horizontal plane. These hollow shafts are placed at an acute angle to each other, their forward ends approaching very close together, while their rear ends are separated 'a considerable distance, as shown in the drawings.

Bevel-gear wheels C D are mounted on the centers of the shafts A B, -being secured thereto and mesh with each other, while with one of such wheels C D meshes another bevel-gear, E, which is secured to a shaft, F.A

' enough to allow the wires to pass through.

'ing a barb these beveled faces ef are in line with each other, or, in other words, are in the same vertical plane. At one edge of the beveled faces ef the tubes G H are provided with triangular lugs g h, projecting a short distance beyond the ends of the tubes. These lugs g h form extensions of the exterior surfaces ofthe tubes, as shown, their outer ends being preferably at right angles to the axes of the tubes. 'Ihe operation of the parts described is as follows: Thefence-wiresIKare drawn through the hollow shafts and the tubes, and astraght barb-wire, L, is laid across them under thelugs g 7L and fiat against the beveled faces e f of the tubes, such tubes being in the position shown in Figs. 1 and 3. The machine is then started, the lugs g h being turned away from each otheraround the outersides ofthe fence-wires, and carrying the ends of the barb-wire around with them. These lugs then turn up through the space between the fence-wires and back to their rst position. The barb-wireisforced by the lugs to follow the beveled faces c f. By means of these beveled faces the barb-wire is not bent directly around the fence-wires and at right angles thereto, but its points are first bent down and to the rear, andare then brought laterally' up between the fence-wires, and are then turned forward into line with each other, as shown in Figs. 4, 5, and 6, thus enabling the fence-wires to be brought close together, and not requiring any shifting of the tubes toward each other during the operation.

I intend to provide my machinewith means for feeding the wire from which the barbs are cutinto position and for cutting off the barbs; but since these means do not form any part of my invention I have not shown them in the drawings or described them in detail herein.

The machine will preferably be run by power, and may have a twisting and spooling mechanism attached,or these operations can be performed separately.

What I claim as my invention isl. In a machine for barbing fence-wires,the combination of the revolving hollow shafts and tubes mounted in stationary bearings in the same horizontal plane and at an vangle to each other, said shafts and tubes being held rigidly against longitudinal or lateral movei ment, and said tubes being provided with lugs for Wrapping the barb-Wire around lshe fencewires, substantially as described and shown.

2. In a machine forbarbingfence-wires, the combination, with the revolvinghollow shafts, located at an acute angle to each other in the same horizontal plane, of the tubes G H, having beveled faces and turning-lugs, and secured in the ends of such shafts, substantially as FRANCIS L. BESTOR.
